请教各位高手：linux 上网设置问题

Gvtheen

我是用unbuntu 7.04,机子cpu是AMD2800+，网卡:realtek rtl8139D（在内核里：有8139cp.ko  8139too.ko，我是在安装时让其自动加载网卡驱动！
我是用静态IP。但一直都无法上网。我ping 自己机子设置的IP，能够到达；但是ping 网关，却不能到达！真的不知道什么原因啊！
肯请高手们帮忙啊！
我用dmesg | grep eth0 得到下列输出

也许是你的网关的问题。把网关IP贴出来让大家帮你pingping看

检查网线。还有交换机。
还有网卡的工作速度，强制成10M半双工试试。

我的机器也出现了类似的情况，不同的是一开始网络是没有问题的，隔一段时间就会出现网络不通的情况，必须先down掉再up才恢复正常！

LS查一下ARP病毒。
